Selection
Transformers are only needed if the systems voltage exceeds the rated
voltage of the drive controller.
For grounded power supply lines, the line voltage is matched to the rated
voltage of the units using autotransformers which are suited to one
specific output voltage range.
To match the voltage for ungrounded power supply lines, always connect
isolating transformers to prevent excess phase to ground voltages.
Autotransformers for Drive Controllers
Select an autotransformer suited to both the line voltage and the power
requirements of the system (see chapter 6.6 "Operation on 400/480 V
Mains").
Autotransformer DST part no.
